I create the bridges in the Dom0 at boot. Put the following in your
/etc/network/interfaces
auto br0
iface br0 inet static
address 192.168.42.10
netmask 255.255.255.0
network 192.168.42.0
broadcast 192.168.42.255
gateway 192.168.42.1
bridge_ports eth0
bridge_stp off
bridge_maxwait 5
The edit the DomU config accordingly:
vif = [ 'mac=00:16:1E:1E:1E:1E, bridge=br0' ]
And in /etc/xen/xend-config.sxp:
#(network-script network-bridge)
(network-script /bin/true)
